Product Introduction

Principle Introduction

• The principle of sub-resonance is adopted, and the excitation force is large. According to the theory of vibration and practical experience, the operating point of the activation feeder is in the sub-resonance range. In this way, it not only takes advantage of the characteristics of the equipment near the resonance point of large excitation force, but also avoids the resonance point, so that the equipment works without resonance, and greatly reduces the loss of the equipment.
• The opening is a large square opening to avoid arching. According to the characteristics of coal, the phenomenon of material arching has a great relationship with the minimum size of the flow section of the silo, and has a small relationship with the flow section. The activation feeder adopts a large square opening, which maximizes the size of the two unilateral sides of the square while increasing the cutting area.
• Special activation block design, large activation area. The activation feeder adopts a special activation block design, which organically combines and separates the blanking part and the activation part, so that the activation area of the upper part of the feeder is large, and the activation can reach 3~4 meters above the feeder inlet, so as to ensure that the coal is not blocked within the height range, and the blanking part is not subject to the pressure of the silo material, so as to ensure that the activated material falls freely and smoothly.
• The matching of the material quantity and the activation amount is reasonable to avoid the more vibrating and more solid the material. The relationship between the amount of blanking and the amount of activation is designed reasonably to ensure that the amount of blanking is greater than the amount of activation, and there will be no accumulation of activated materials at the discharge port due to untimely blanking, resulting in agglomeration, thereby blocking the channel.
